Careful with those 14500s. Amp limits tend to be pretty low. Even the AWs should only pull 4.8 amps.
You're really asking for something bad to happen, especially assuming you're using the standard AW's. The AW 14500's are rated at 4A (some people will quote it as 8C which is 4.8A, but AW says "4.0A"). 4A is the maximum current you should be drawing from that battery. At 0.7 ohms, you're drawing 6A - 50% more than the maximum that battery can safely handle. You really shouldn't sub-ohm on a 14500.
The Nemi-clone should have come with an additional ring to allow it to accept 14650 cells. I've found conflicting information regarding the Efest 14650's - 5C vs 10C, so it's best to err on the side of safety and assume 5C. That allows a minimum build of .88 ohms.
Here's my copper clone army. Current favorites are the Cartel+Stillare and Vanilla+Plume Veil. Emma+Zenith is up there too. The Hades+Tobh is my fog machine.

What's the RDA on your Emma?
It's a Zenith v2.5 from angelcigs. Same place the Emma clone came from. It's quite good! Juice well could be a bit deeper, but the flavor is great and the clouds are very decent for a non-cloud-chaser atty.
Good God man, you must be cleaning copper nonstop!
